BITSAT Physics Question (2024) — Solution

Question

A plane progressive wave is given by y=2 2 (330 t-x) m . The frequency of the wave is:

Options

  1. A. 165 Hz
  2. B. 330 Hz
  3. C. 660 Hz
  4. D. 340 Hz

Answer

B. 330 Hz

Step-by-step solution

Equation of wave is, y=2 2 (330 t-x) m y=A ( t-k x) On comparing =2 330 2 f =2 330 f =330 ~Hz [ =2 ~F ]
